AUTOMATIC FIRE-ALARM.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Application led August 10,1905. Serial No. 273,652.

and exact description of the invention, such as will enable others skilled in the art to 1 9 be which it appertains to make and use the same.

This invention relates to improvements in automatic fire-alarm devices.

The object of the invention is to provide a` device of this character constructed and arrangedso that should a firebreak out inproximity to any one of a series of actuating devices said mechanism will be automatically operated to sound an alarm.

A further object is to provide a device of this character which will be simple and inexpensive in construction, reliable in operation, easily set up, and extended to various parts of a building.

With the above and other objects in view the invention consists of certain novel features of construction, combination,I and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a diagrammatic view of the device, showing the manner in which the same is arranged. Fig. 2 is an enlarged detail view of the alarmbox with the cover of the same removed and showing the arrangement of the alarm mechanism therein, and'Fig. 3 is a vertical sectional view through the same.

-Referring more particularly to the drawings, 1 denotes an alarm-box, which may be of any design and shape. In the box 1 is arranged a horizontally-disposed shaft 2, on which is revolubly mounted a wheel 3, said wheel being provided with an extended hub forming a winding drum or spool 4. vTo the periphery fof the wheel 3 is adapted to be secured a series of sounding devices, which are here shown and are preferably in the form of bells 5.

Adapted to be wound upon the spool or drum 4 is a cord or strap 6. Said cord passes from the spool 4 over a guide-pulley 7 and combustible cords 9, said cords being supported and guided in suitable staples or pulleys 10 and are secured at one end to nails or other suitable fastening devices 12. To the pposite end of the cord or cords is secured a weight or weights 13, said weights being suspended immediately above the cup-shaped receptacle 8, whereby should any of the cords burned and broken the weight attached to the end thereof will drop into the receptacle 8, causing thesame to drop or lower, thus unwinding the cord or strap 6 from the spool or drum 4. The unwinding of the cord or strap 6 will cause a rapid revolution of the spool 4 and the wheel 3, which movement of the wheel will cause the bells or other devices to be sounded, thus alarming the occupants of the building and notifying them that a iire has occurred in some part of the building.

4An alarm device constructed as herein shown and described may be applied to one room or to a number of rooms in a building or run from one building to another, and while but one cord and weight is here shown 'it is obvious that a number of such cords and weights may be run from above the receptacle 8, so that all parts of a building may be protected, it being necessary for but one of said cords to be broken in order to cause the sounding ofthe alarm.

From the foregoing description, taken in connection with the accompanying rawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a iire-alarm of the character described, the combination with a revolubly-mounted wheel, of bells secured thereto, a winding drum or spool formed on the extended hub of said wheel, a cord or strap adapted to be wound on said drum or spool, a guide-pulley around which the free end of said cord is has secured to its free end a cup-shaped rel adapted to pass, a receptacle secured to said ceptacle S. Adapted to be run to various parts of a room or building is one or more free end of the cord, a suitably-supported combustible cord adapted to be stretched IOO sounding said bells, substantially as described.

In testimony whereof have herento set my hand in presence of tWo subscribing Wt- 1o nesses.
